With the rapid development of precision molds, my country's precision mold industry has been at the forefront of the world. At present, my country's precision molds have the four characteristics of wear resistance, strength and toughness, fatigue fracture performance, and high temperature performance. Here are the four characteristics of precision molds.

Four characteristics of precision molds

1. Wear resistance

When the blank is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing severe friction between the surface of the cavity and the blank, which causes the mold to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold.

Hardness is the main factor affecting wear resistance. In general, the higher the hardness of the mold parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.

2. Strength

The working conditions of the molds are mostly very bad, and some often bear a large impact load, which leads to brittle fracture. In order to prevent sudden brittle fracture of mold parts during work, precision hardware molds must have high strength and toughness.
